Sergeant major

Sergeant major is a senior non-commissioned rank or appointment in many militaries around the world. In Commonwealth countries, the degrees of sergeant major are appointments held by warrant officers. In the United States, there are various grades of sergeant major. In 16th century Spain, the mayor was a general officer. He commanded an infantry, and ranked about third in the armys command structure. In the 17th century, sergeant majors appeared in individual regiments and these were field officers, third in command of their regiments, with a role similar to the older, army-level sergeant majors. The older position became known as sergeant major general to distinguish it, over time, the term sergeant was dropped from both titles, giving rise to the modern ranks of major and major general. It is about time that the U. S. and British histories of the title diverge. A sergeant major is an appointment, not a rank and it is normally held by the senior warrant officer of an army or marine unit. These appointments are made at several levels, for example, the warrant officer of a company, battery or squadron. The title normally consists of the title followed by sergeant major. A sergeant major of a regiment or battalion is known as a sergeant major. In the Australian Defence Force, in addition to CSMs and RSMs, Sergeant majors are normally addressed as sir or maam by subordinates, and by Mr or Ms by superiors, with the term RSM/CSM/etc reserved for the sergeant majors commanding officer. In the British Armed Forces, the plural is sergeant majors, the appointment of sergeant major is given to the senior non-commissioned member within sub-units, units and some formations of the Canadian Army. The regimental sergeant-major is the sergeant major in a battalion-sized unit, including infantry battalions and artillery, armoured, engineer. This appointment is held by a chief warrant officer. The same position can also be held by a warrant officer in anticipation of promotion. In artillery batteries, this appointment is known as battery sergeant-major, while in units with a cavalry heritage, company sergeant-majors and their equivalents are normally addressed as Sergeant-Major or by rank

Specialist (rank)

Specialist is a military rank in some countries armed forces. In the United States military, it is one of the four junior enlisted ranks in the U. S. Army, above private first class, unlike corporals, specialists are not considered junior non-commissioned officers. Specialist E-4 is the most common rank that is held by US Army soldiers, in 1920, the Army rank and pay system received a major overhaul. The second grade had two titles, first sergeant, which was three stripes, two rockers, and a lozenge in the middle, and technical sergeant, which was three stripes and two rockers. By World War II, the rank of first sergeant had been elevated to first grade, the wearing of specialist badges inset in rank insignia was abolished, and a generic system of chevrons and arcs replaced them. From 1920 to 1942, there was a rank designated private/specialist that was graded in six classes and they were considered the equal of a private first class, but drew additional specialist pay in relationship to the specialist level possessed on top of their base Pfc. pay. Unofficially, a private/specialist could be authorized, at his commanders discretion, on 8 January 1942, the rank of technician was introduced to replace the private/specialist rank, which was discontinued by 30 June 1942. This gave technical specialists more authority by grading them as non-commissioned officers rather than senior enlisted personnel and they were parallel to pay grades of the time, going up in seniority from technician fifth grade, technician fourth grade, and technician third grade. To reduce the confusion caused in the field, an embroidered T insignia was authorized for wear under the chevrons on 4 September 1942. The rank was finally discontinued on 1 August 1948, on 1 July 1955, four grades of specialist were established, Specialist Third Class, Specialist Second Class, Specialist First Class, and Master Specialist. The insignia was yellow on a blue background. The senior specialist ranks of SP2, SP1, and MSP were indicated by one, in 1956 the Army Green uniform was adopted. The enlisted stripes were changed from yellow on a backing to Goldenlite Yellow on a green backing. The specialist insignia was redesigned to be larger, broader, in 1958 the DoD added two additional pay grades to give enlisted soldiers more opportunities to progress to a full career with additional opportunities for promotion. The Super Grades of Spec. /8 and Spec. /9 were respectively given one, in 1978 the specialist rank at E-7 was discontinued and in 1985, the specialist ranks at E-5 and E-6 were discontinued. These specialist ranks were created to reward personnel with higher degrees of experience, appointment to either specialist or non-commissioned officer status was determined by military occupational specialty. Different military occupational specialties had various transition points, for example, in the band career field, a bandsman could not achieve non-commissioned officer status until pay grade E-6 was attained. In some military occupational specialties, a soldier was appointed either a specialist or non-commissioned officer depending on particular position or slot that he filled in his organization

Sergeant

Sergeant is a rank in many uniformed organizations, principally military and policing forces. Its origin is the Latin serviens, one who serves, through the French term sergent, the term sergeant refers to a non-commissioned officer placed above the rank of a corporal and a police officer immediately below a lieutenant. In most armies the rank of sergeant corresponds to command of a squad, in Commonwealth armies, it is a more senior rank, corresponding roughly to a platoon second-in-command. In the United States Army, sergeant is a junior rank corresponding to a four-soldier fireteam leader. More senior non-commissioned ranks are often variations on sergeant, for example staff sergeant, many countries use sergeant rank, whether in English or using a cognate with the same origin in another language. The equivalent rank in Arab armies is raqeeb, meaning overseer or watcher, in medieval European usage, a sergeant was simply any attendant or officer with a protective duty. Any medieval knight or military order of knighthood might have sergeants-at-arms, the etymology of the term is from Anglo-French sergant, serjant servant, valet, court official, soldier, from Middle Latin servientem servant, vassal, soldier. Later, a sergeant was a man of what would now be thought of as the middle class. Sergeants could fight either as heavy to light cavalry, or as well trained professional infantry, most notable medieval mercenaries fell into the sergeant class, such as Flemish crossbowmen and spearmen, who were seen as reliable quality troops. The sergeant class was deemed to be half of a knight in military value. A specific kind of military sergeant was the serjeant-at-arms, one of a body of armed men retained by English lords, the title is now given to an officer in modern legislative bodies who is charged with keeping order during meetings and, if necessary, forcibly removing disruptive members. The responsibilities of a sergeant differ from army to army, there are usually several ranks of sergeant, each corresponding to greater experience and responsibility for the daily lives of the soldiers of larger units. Sergeant is a rank in both the Australian Army and the Royal Australian Air Force, the ranks are equivalent to each other and the Royal Australian Navy rank of petty officer. The Australian Army rank of sergeant is now redundant and is no longer awarded, due to being outside the rank equivalencies. Chief petty officers and flight sergeants are not required to call a warrant officer class two sir in accordance with Australian Defence Force Regulations 1952. The rank of sergeant exists in all Australian police forces and is more senior than a constable or senior constable, New South Wales Police Force, for example, has the additional rank of incremental sergeant. This is a progression, following appointment as a sergeant for seven years. An incremental sergeant rank is less senior than a senior sergeant but is more senior than a sergeant, upon appointment as a sergeant or senior sergeant, the sergeant is given a warrant of appointment under the commissioners hand and seal
